[0003] However, with the continuous expansion of the scale of aquaculture, the discharge of aquaculture effluent is increasing day by day. Aquaculture effluent contains a large amount of organic pollutants such as leftover bait and feces. If it is discharged directly without treatment, it will cause serious environmental problems such as eutrophication of water bodies. Therefore, the treatment of aquaculture effluent has become a hot issue that has attracted widespread attention both inside and outside the industry.
